Filter by:Cough is the most common presenting symptom to family physician. Chronic Cough affects approximately 10-12% of the general population and is one of the commonest reasons for referral to secondary care. Unfortunately, there are no licensed treatments for this debilitating condition, which is associated with a poor quality of life, affecting the social, physical and psychological well-being of patients. The aim of this single-centre proof-of-concept study is to investigate whether mepolizumab reduces objective cough frequency in patients with eosinophilic asthma and non-asthmatic eosinophilic bronchitis presenting with chronic cough. Secondary outcomes including the effects on quality of life, the intensity of irritant sensations, airway hyper-reactivity and inflammatory cells and their progenitors will also be evaluated. The investigators hypothesize that in patients with asthma and non-asthmatic eosinophilic bronchitis, eosinophils are involved in sensitizing airway nerves and thereby increasing spontaneous objective coughs. The investigators predict that treatment with mepolizumab will reduce airway eosinophilia in patients with chronic cough due to eosinophilic asthma and non-asthmatic eosinophilic bronchitis, thereby causing a reduction in objective cough frequency.
Chronic cough is a common troublesome symptom which has a global prevalence of approximately 10%, but with wide variations across continents. The aim of this study is to evaluate the effectiveness of treatment, patient-reported outcomes and burden of disease in patients with chronic cough referred to a specialist clinic. The proposed study will use pre-defined diagnostic criteria, investigations and treatment algorithms such that all recruited patients will undergo the same investigations and follow a set management algorithm. This study will objectively and subjectively assess coughing at baseline and after treatment in a real-world clinical setting. This will allow us to understand the relationship between any objective reduction in cough after treatment, and whether this translates to any significant improvement in subjective questionnaire scores. We will assess the impact of health conditions on lost productivity in monetary units and assess the amount of absenteeism, presenteeism and daily activity impairment attributable to unexplained chronic cough/refractory chronic cough. Finally, a patient survey at the end of the study will evaluate the patients' satisfaction and experience of investigation, management trials and use of questionnaires.
A prospective, multi-center, observational clinical trail. Aim to evaluate the real incidence of COPD pertussis and the impact of pertussis on subaute cough.
The purpose of the study is to investigate the addition of high frequency chest wall oscillation (HFCWO) therapy to the prescribed care regimen to support the diaphragm during airway clearance among post-COVID patients with COPD and chronic productive cough as a way to limit the advancement of pulmonary symptoms and need for critical services during recovery from COVID-19.
The primary objective of this study will be to evaluate the efficacy of gefapixant (MK-7264) in reducing cough frequency as measured over a 24-hour period. It is hypothesized that at least one dose of gefapixant is superior to placebo in reducing coughs per hour (over 24 hours) at Week 24.
BAY1817080 is currently under clinical development to treat pain related to unexplained chronic cough or chronic cough not affected by a treatment (refractory and/or unexplained chronic cough, RUCC), or a condition where the bladder is unable to hold urine normally (overactive bladder, OAB) or a condition in which tissue similar to the tissue that normally lines the inside of the womb grows outside the womb (endometriosis). Especially in elderly patients with OAB or RUCC, renal impairment is frequent. Renal impairment which co-occurs in especially in elderly patients with OAB or RUCC is a common condition in which the kidneys are not filtering the blood as well as they should. End stage renal disease (ESRD) requiring hemodialysis is a condition in which patients kidneys are no longer able to work as they should and require treatment to filter wastes from the blood. The goal of the study is to learn more about the safety of BAY1817080, how it is tolerated and the way the body absorbs, distributes and excretes the study drug given in men and women with moderate renal impairment and with those who have end stage renal disease (ESRD) requiring dialysis compared with matched participants with normal kidney function.
The purpose of this study is to evaluate the efficacy and safety of gefapixant in participants with recent onset chronic cough (duration >8 weeks after onset of cough symptoms) for <12 months and a diagnosis of refractory or unexplained chronic cough. The primary hypothesis is that gefapixant is superior to placebo in improving cough-related quality of life measured as change from baseline in the Leicester Cough Questionnaire (LCQ) total score at Week 12.
The purpose of this study is to evaluate the efficacy and safety of gefapixant, in improving symptoms of cough-induced stress urinary incontinence (SUI) in adult female participants with refractory or unexplained chronic cough. The primary hypothesis is that gefapixant is superior to placebo in reducing the frequency of cough-induced SUI episodes over 12 weeks.
The primary objective of this study is to determine the optimal dose of S-600918 in patients with refractory chronic cough by evaluating the change from baseline in 24-hour cough frequency (coughs per hour) with S-600918 compared with placebo.
Idiopathic pulmonary fibrosis (IPF) is a rare, progressive life-threatening disease that is characterized by exertional dyspnea and persistent dry cough. Cough in IPF is both a presenting and a complicating clinical feature, which affects approximately three quarters of IPF cases. It is often a debilitating symptom that adversely affects quality of life (QoL) and is usually refractory to medical therapy. Inhaled RVT-1601 (formerly, PA101B), a new inhalation formulation of cromolyn sodium delivered via the eFlow® Closed System (CS) nebulizer, is being evaluated in this Phase 2b study for the treatment of persistent cough in patients with IPF.
